Why should we learn React JS?

Why should we learn React JS ? Many of us might got the same doubt. Right? Let’s know some reasons to learn React JS.

It’s Fast

This is probably the top reason JavaScript programmers are looking to start writing their applications using the React library. Utilizing a virtual copy of the DOM, it is designed to perform operations virtually before they are rendered to the standard JavaScript DOM tree.

This isn’t just a numbers game. It’s surprising that moving UI operations to virtual DOM actually changes how your application feels for the end-user. You’ve probably already started noticing this phenomenon across the web on websites such as Netflix.



Modular Design

React supports modular design that is often associated with building large, scalable applications. The reason for this is the advent of EcmaScript 6 specification that came out in 2015 which provides new syntax that favors modular methodology.

For example, the required (ES5) and includes (ES6) keywords tie together not only files alone but assume a class-based relationship between objects.

And even though as of this writing include keyword is not supported in modern browsers (even Chrome) we can begin writing modular programs by either using require or transpiring our ES6 code to ES5 (that almost all browsers do understand by now) before sending it to the browser for rendering.

When browsers catch up, we will no longer have to transpile. When this takes place, React will become an even more common library you’ll see everywhere. Eventually, modular JavaScript program design will become the norm with or without React.

 Scalability

In React each HTML element is treated like a programmable component that can be nested within other compo nested. Child components have parent components associated with them.

The relationship between parent and children components is established through something known as props. Scalability of React programs is achieved by making each component a conglomerate of HTML, CSS, and JavaScript code.

Flexibility

React is more than just a UI view library as opposed to what you will probably hear at first when you start figuring it out. And that isn’t entirely wrong. React gives us the ability to create lightning-fast interactive components that can be used as elements of your application.

However, React’s utilizes the principle of render targets which allows you to send the result of your code to just about anywhere, included but not limited to front-end view.

Popularity Among Employers

React was developed by programmers at Facebook after years of studying web applications. More or less, it originated from a set of proven software engineering philosophies. Although, many of the most traditional JavaScript programmers will not be fa familiar with it.

When you are learning React, you are learning computer programming principles, not just a list of functions and methods, which is the case with other libraries such as jQuery.

In 2016 JavaScript has become the leading language for front end web development. Having React on your resume gives you an edge over your competition if you’re looking for employment in the software industry. The average Sr.JavaScript programmer in the San Francisco Bay Area makes $120-150K a year.
